Check all fuses to include those in engine bay, then all connections of battery cables - not just the ones at the battery posts.
Start using a little logic and find out what's wrong before replacing more parts. Power directly to the low side of the solenoid should force the starter. If that works but the starter doesn't work with the keyswitch, it might just be the neutral lockout.
Follow the + battery cable from battery should connect to starter solenoid (relay)
On my 1995 Ford Explorer , as far as I know , the starter solenoid is mounted on the starter and the starter relay ( which most people just refer to as the solenoid ) is mounted near my battery and has the positive battery cable connected to it ( a relay is a low voltage switch ) P.S. I'm not a mechanic / technician
If it is like my '86 Samurai there is no starter relay. It uses a starter solenoid on the top of the starter to pass battery to starter motor when the solenoid is activated via the key switch.
Maybe on the top of the starter - follow the + battery cable it will connect to the starter relay (solenoid)
You should locate and test the solenoid. Most have three connections. There is a large cable from the battery to the solenoid, from the solenoid to the starter and from the start switch to the solenoid. The power terminals to the battery and the starter are large and have large cables. The starter switch connection is much smaller. Turning the key to 'start' provides a low current voltage to the solenoid causing the solenoid relay to close and power from the battery cable to connect through to the starter. If that voltage is present then the solenoid or the wiring between the solenoid and battery or solenoid and starter is suspect. If that voltage is missing then the starter switch or solenoid feed line may have failed.
Follow the + battery cable should connect to the starter solenoid (relay) either at the top of starter or at the inner fender perhaps under battery
The starter relay ( solenoid ) is mounted near the battery on the inside of the drivers side fender
The starter solenoid shows to be on top of starter. If you don't know where the starter is located, follow the positive battery cable. You may have to get under vehicle to get at the starter. I replace starter and solenoid as a unit. Now, if your talking about starter relay that is a different animal.
you need to replace the starter solenoid usually on a ford the solenoid is located on the side of the engine bay

In the Power Distribution Box in the engine compartment Relay # 6 is the starter relay Caution : The PD Box is " live " ( I believe it was 1998 that Ford changed the Explorer from the solenoid / relay switch mounted on the inside of the drivers fender , near the battery to a plug in style in the PD Box )
Follow the + battery cable - should connect to the starter solenoid (relay)
Postive battery cable should connect to the starter relay (solenoid)
The relay is separate from the actual "starter solenoid" which is found at the top of the starter (along the + battery cable).
